Description

Technical Field

[0001] The utility model relates to the technical field of oil smoke separation, in particular to an oil smoke separation device for a range hood. Background Art

[0002] Existing fume separation nets are simply metal grilles or meshes with no automatic degreasing function. They need to be manually disassembled and cleaned, which is very time-consuming and labor-intensive. Furthermore, although existing fume separation nets are relatively large, they are overly dispersed in design and not centrally located along the path through which the fume passes. Consequently, the condensation separation area that actually functions is too small, resulting in low fume separation. Long-term, high-concentration fume passing through the impeller and adhering to it can rapidly reduce the range hood's suction power, increase noise and vibration, and severely shorten the range hood's service life. Therefore, to address the technical issues of low fume removal efficiency in existing range hoods and noise caused by fume adhering to the separation net, the present invention provides a range hood fume separation device.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] like Figures 1 to 7 As shown, this embodiment provides a range hood oil fume separation device, comprising: a box body 1 and a separation mechanism installed in the box body 1; the box body 1 is installed on the inner side of the vertical ventilation duct of the range hood; an air outlet and an air inlet are respectively provided at the upper and lower ends of the box body 1; an upper U-shaped support rod 11 and a lower U-shaped support rod 12 are respectively installed at the upper and lower ends of the box body 1; specifically, the box body 1 is composed of a rectangular frame, an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate respectively have an air outlet and an air inlet; the upper cover plate and the lower cover plate respectively have a U-shaped support rod 11 and a lower U-shaped support rod 12; the box body 1 is a rectangular box structure, which is suitable for being installed in the vertical ventilation duct of the range hood, and the oil fume enters the box body 1 through the air inlet below, is adsorbed and separated by the separation mechanism, and then flows out from the air outlet.

[0026] See also Figures 2 to 6As shown, the separation mechanism includes a prismatic shaft 21, an oil suction plate 22, and an oil scraper rod 23. The prismatic shaft 21 is rotatably mounted between the bottom bars of the upper U-shaped support 11 and the bottom bars of the lower U-shaped support 12. Several oil suction plates 22 are evenly distributed and axially mounted around the prismatic shaft 21. Specifically, a prismatic hole is defined at the center of each oil suction plate 22. The oil suction plates 22 are sleeved around the prismatic shaft 21 to ensure that the prismatic shaft 21 stably drives the oil suction plates 22 in rotation. Several scraper rods 23 are evenly distributed along the axial direction around the prism shaft 21. Specifically, a circular hole is provided at the center of the scraper rod 23. A matching ring 231 is installed inside the circular hole. The inner side of the ring 231 is a prism hole, and the ring 231 is sleeved on the outer side of the prism shaft 21. Vertical limiting grooves 13 are provided on the opposite inner walls of the box body 1. The ends of the scraper rod 23 are correspondingly slidably matched and installed in the vertical limiting grooves 13. The provision of the ring 231 and the vertical limiting grooves 13 ensures that the scraper rod 23 does not rotate synchronously with the prism shaft 21, thereby achieving the purpose of scraping oil from the surface of the oil suction plate 22. The oil suction plate 22 and the scraper rod 23 are installed at intervals. Specifically, the oil suction plate 22 is on top and the scraper rod 23 is on the bottom, and they are installed in sequence at intervals. The scraper rod 23 is attached to the lower surface of the oil suction plate 22. The scraper rod 23 located between two adjacent oil suction plates 22 is attached to both the upper and lower oil suction plates 22, achieving a good oil scraping effect. More specifically, the upper and lower portions of the prismatic shaft 21 are threadedly connected to fastening nuts 24. This threaded connection ensures stable mounting of the oil suction plate 22 and the oil scraper rod 23, allowing the oil scraper rod 23 to attach to the oil suction plate 22, facilitating oil scraping. The upper surface of the oil suction plate 22 is evenly distributed with a plurality of arc-shaped ventilation holes 221. Specifically, arc-shaped baffles 222 are formed between adjacent arc-shaped ventilation holes 221. The arc-shaped ventilation holes 221 and arc-shaped baffles 222 on adjacent oil suction plates 22 are spaced apart, ensuring good ventilation while allowing gas containing oil smoke to pass through the multiple oil suction plates 22 in sequence, effectively adsorbing and scraping the oil smoke. The prismatic shaft 21 is driven to rotate by a drive mechanism, specifically a reduction motor 3. The output end of the reduction motor 3 is connected to the prismatic shaft 21. The reduction motor 3 provides stable driving force while also rotating at a low speed, meeting the requirements of the oil scraper rod 3 for oil scraping.

[0027] In the present invention, oil smoke enters the housing 1 under the action of the exhaust system of the range hood. The oil smoke is effectively absorbed by the multiple oil suction plates 22, and the reduction motor 3 drives the oil suction plates 22 to rotate, enabling the scraper rods 23 to effectively scrape the oil from the oil suction plates 22, thereby improving the range hood's oil smoke removal efficiency and reducing noise. Furthermore, the arc-shaped ventilation holes 221 and arc-shaped baffles 222 on two adjacent oil suction plates 22 are spaced apart, ensuring good ventilation while allowing the gas containing oil smoke to pass through the multiple oil suction plates 22 in sequence, effectively absorbing and scraping the oil smoke.

[0028] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
